IMPROVEMENT IN NUMBERING- MACHINES.

Specification forming part of Letters l atent No. 155,765, dated October6, 1874 application filed April 13, 1874.

To all whom it may concern:

Be' it known that I, JAMES D. SMITH, of Washington, in the county ofWashington and District of Columbia, have invented certain new anduseful Improvements in Numbering-Machines; and I do hereby declare thatthe following is a full'an'd exact description thereof, reference beinghad to the accompan'ying drawings making a part of this application.

My invention relatesto machines for numbering bank-notes, certificates,&c., in regular order. It has for.v its object to adapt the machine touse by steam or other power; and consists in the improvements as will behereinafter more fully set forth.

To enable those skilled to fully understand the same, I will proceed todescribe the construction and operation, referring, by-letters, to theaccompanying drawings, in which- Figure 1 is a side elevation of amachine embracing my invention. Fig. 2 is a rear view. Fig. 3 is a topview; Fig. 4, a similar view of the treadle and its connection with thepulley and driving-wheel; Fig. 5, a top detail view of theinking-rollers and frame; Fig. 6, detail view of rotating inking-plate;Fig. 7, a detail and section of one of thebumpers. Fig.8 is an enlargedview of the inkfountain; Fig. 9, a side view of the ordinary 'footdriving device, adapted to be substituted for the power mechanism; andFig.- 10 is an enlarged detail view of the semi-universal jointat therear end of the walking-beam lever.

Similar letters indicate like parts in the several views.

A is the frame of the machine, adapted to be secured at the corners tothe floor in the usual manner. B is the bed or table, which is capableof adjustment throughthe medium of two slotted hangers, G G, at thefront end, with thumb-screws c 0 taking in the front legs of the frame,and by a screw-rod, D, running in the upper brace at the center thereof,as fully illustrated at Figs. 1 and 2, and is old.

' E is the platen, arranged as usual. The frame Ais extended upwardly,as clearly shown at A,

Figs. 1 and 2, having a vertical slot in its forward end to guide thevertically-movin g rod F, which carries the type-arbor G. It isbifurcated to admit of the reciprocation of the arm B of theinking-carriage, and provided at H with a pivot-bearing for thewalking-beam 1ever I. To the rear side of this extension of the frame issecured a bracket, J, to which is pivoted, at a, a bell-crank lever, K,of the design shown at Fig. 1, having its ends slotted, as seen. Lowerdown is secured a horizontal bracket, L, forming a rear guide andsupport for the arm of the inking-carriage, which has its forward endsuitably supported within the bifurcated portion of A. The walking-beamlever I has a hanger, M, near its rear end,with a wrist'pin, b,extending into the slot in the upper end of the bell-crank lever K, andthe inking-carriage arm B is provided with a similar pin, d, projectinginto the slot in the lower end of said lever, so that it will be seen,inthe travel of thewalkin'g-beam lever, the arm B, through the medium ofthe slotted bellcrank lever and pins 1) and d, is made to reciprocatehorizontally to cause a proper distribution of the ink on the ink-plateN, also the type; and it will be seen that by the curved direction of'the slot in the upper end of the lever K therear end of the walking-beamlever I may continue to rise after the motion of the inking carriage armhas suspended. Suitable bumpers e fare provided to prevent any jar tothe levers. The bearings of the carriage-arm are composed ofanti-friction rollers. The inking-rollers are secured in a frame secured'to the arm B. This frame is made in two parts, as it were. The rearhalf 1 is pivoted to the head at 3, and the forward half 2 is pivoted at4 to the forward ends of the rear half of the frame, and may be securedin any given relation thereto by a set-screw, by which the joint may berigid or pivotal, in order that the two parts or sections 1 2 may bear.a fixed relation to each other, or be capable of a somewhat independentvertical movement, one or both sections being under the influence of thesprings g, according to circumstances, and the drop of the combinedframe is regulated by the ordinary set-screws passing through the headfrom the rear. Springs gg, made fast at one endto the head, have theirfree ends pressingdownwardly upon suitable projections on the forwardend of the frame back to its horizontal or normal position after it hasbeen raised by the inclines,

as will be more fully set forth hereinafter, the whole frame swingingupon the pivot 3, and by means of the construction of the rollerframethe inking-rollers can be readily read-- justed, &c., so that they willalways reach and perfectly ink the type; O O are-the inking adapted toride upon a beveled road, 6, at the lower end of hangers P P, the objectand result of which are that, as the carriage goes forward, the friction-rollers, riding up the incline,

lift the forward end of the carriage or frame, and thus, also, theinking rollers, thereby causing a more perfect inking where the type isof extensive Widths. This, however, may be dispensed with by simplyremoving the hangers P P, which are secured by screws for that purpose.To the rear and to one side of the carriage-head is secured a suitablebracket, Q, to which is secured a spring-pawl, j, that catches in thecircular ratchet on the under side of the inking-plate, and thus rotatesit a given distance on the retreat each time of the carriage. On theopposite side of the head is another pawl, k, adapted to strike thespurwheel I on the shaft of aroller, m, in an ink: fountain, n, so thatat every return movement of the carriage, the roller m, which takes itssupply from the fountain n, presents a new surface, against which oneheel of the rear inking-roller 0 comes in contact, and from which itreceives its supply to distribute. This fountain n is made adjustable onthe inkingplate support, so that a greater or less area of contactbetween the roller 0 and the fountainroller on may be secured, and thusa greater or less quantity of ink taken up and distributed. The rear endof the walking-beam lever is connected to the pitman R by a bolt, asclearly seen on enlarged scale at Fig. 10.

I This bolt, as will be seen, is enlarged in the center, so as topresent a partial sphere, which is passed into the greatest diameter ofa slot in the end of the lever, and a quarter-turn given, which turnsthe curved surface of the bolts center within a coinciding surface inthe lever, thus forming a sort of ball-and-socket joint, the bolt beingretained laterally by the enlarged center, and against rotation by afeather passing in through a notch in the head into the bifurcated headof the pitman. By this connection it will be seen that the necessaryvibration of the pitman in its rise and fall is compensated for. Thelower. end of the pitman is connected to an adjustable wrist-pin in thecrank-plate R on the rear end of the driving-shaft S, which has its rearbearing in a box mounted in a platform-bracket, T, and its forward endin a similar box mounted on a suitable cross-tie, U. An ordinary looseconepulley is arranged on the shaft S, and adapted, by a foottoggle-joint lever, to be thrown in contact with a fixed pulley, V, sothat by friction the power applied to the cone-pulley is transferred tothe pulley V and the shaft S, thus causing the movement of all the partsof the machine. Arranged upon thetop of the bracket T is an adjustablearm, carrying a curved friction-brake, W, which may be made to exerciseany given control over the movementof the pulley V after breaking itsfrictional contact with'cone-pulley, so that when the foot is raised forthe purpose of stopping the machine, the natural impetus which wouldinduce to the movement of the walking beam and v the automatic change ofthe type is arrested by the friction-brake W. X is a heel-rest securedin proper relation to the front end of the foot-lever, and has arrangedthereon a setscrew or rod, Y, which may be run up or down,

and secured in position by nuts 19 p. This screw or rod is arrangedunder the end of the lever, and controls the stroke or downward.movement of the end of said lever, in the end of which is arranged aroller, Z, which will rotate under the foot, and thus avoid the tendencyof pushing the foot back, so that a fixed or given relation between theoperatives foot and the end of the lever may be maintained. On the underside of this foot-lever, and at its forward end, isarranged a slidingbolt, of suitable thickness, adapted to be thrown forward by theoperative, so that it shall come between the lower side of the lever andthe top of the screw or rod Y, so that the stroke of the lever necessaryto produce such friction as would induce to a movement of the machine isinterdicted. The object of this arrangement is to prevent the accidentalmovement of the machine when not engaged in numbering, and thus preservethe proper numbers for the continuation of a series.

It will be seen that the whole power driving device may be readilyremoved, and the ordinary foot driving device, as shown at Fig. 9, v

substituted.

The rear anti-frictional bearing of the carriage-arm B is constructed asshown, so that the upper roller can be dropped down, to compensate forwear, by loosening the screws 7' 7', which pass through elongated slotsin the side plates 8, which, with the roller that has its bearin gstherein, may be lowered and again rigidly secured in position.

I h ve'described novel construction of treadle, friction-brake,heel-rest, and semi-universal joint between the pitman and the end ofthe walking-beam lever as features specially adaptable and valuable in anumbering-machine, but lay no claim to them here, as I contemplatemaking a new application covering these features of invention,irrespective of their special application.

What I claim as new, and desire to secure by Letters Patent, is-

1. In combination with the levers I and arm B, provided with suitablewrist-pins b d, the bell-crank lever K, constructed as described, forthe purposes set forth.

2. The frame for the inkin g-rollcrs, com posed of two sections, 1 2,secured together by screwpivots 4, and to the head of the carriage, in

combination with the springs g, substantially as and for the purposesset forth.

3. In combination with the inking-frame,

' constructed as described, the inclined ways i on hangers P; to throwup the forward roller, that it may follow the upward movement of thearbor G, as and for the purposes described.

4. In combination with the reciprocating arm 13 of a numbering-machine,the adjustable anti-friction bearings s 1', whereby theplane in whichthe inking-carriage is moved maybe
